It depends. Typically about 30 - 40 per hour, but if one specific person plays it becomes more like 15 - 20 per hour. The guy takes 5 minutes to decide if he'll call the blinds pre-flop! And no wants to enforce a time rule b/c they're all chicken S. I think he just got banned though, as long as people can stick by their decisions.
sometimes it can be awhile i mean this one guy always takes 3 minutes to decide if he;ll call or fold the blind. and he always puts the wrong chips. kinda funny.
this one guy i play with always takes 3-5 min to put in his preflop bet, he always has to choose the perfect combination of chips.... takes forever...and its annoying....but kinda funny...
